[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example

[0022] Please see Figure 1-4 The present invention provides the following technical solution: A sanding belt support frame for a knife sharpener includes a base 1, a motor bracket 16 connected to one end of the base 1, a motor 4 fixedly connected to the motor bracket 16, a drive wheel 9 and a driven wheel 10 fixed to the motor 4, and a second bracket 8 for mounting the driven wheel 10. The drive wheel 9 and the driven wheel 10 are provided with sanding belts. An adjustment seat 12 is stacked on the base 1. One end of the adjustment seat 12 is movably connected to the base 1 via a vertical shaft 7. The other end of the adjustment seat 12 is provided with an adjustment component for adjusting the adjustment seat 12 to rotate in accordance with the base 1. The second bracket 8 is connected to the adjustment seat 12.

[0023] In use, by setting up the base 1 and stacking the adjustment seat 12 on top, the driven wheel 10 is connected to the adjustment seat 12. By adjusting the adjustment seat 12 and making it rotate around the vertical axis 7, the relative position of the driving wheel 9 and the driven wheel 10 can be changed. Therefore, the sanding belt can be adjusted to the left or right, so that the sanding belt no longer deviates.

[0024] Preferably, the adjustment assembly includes a first bracket 2 fixedly connected to the base 1 and an adjustment rod 6 slidably connected to the adjustment seat 12 with a single degree of freedom. The adjustment rod 6 passes through the first bracket 2, and a wing nut 5 is threadedly connected to the portion of the adjustment rod 6 extending out of the first bracket 2. In use, rotating the wing nut 5 will cause the adjustment rod 6 to extend out of the first bracket 2 to varying lengths. When it extends further, the adjustment rod 6 will drive the adjustment seat 12 to rotate outward, while the adjustment rod 6 slides outward on the adjustment seat 12 to adapt to this adjustment. Furthermore, the above-mentioned solution of this utility model can achieve adjustment simply by rotating the wing nut 5, making the adjustment method convenient and the operation simple.

[0025] Based on the above solution, the connection between the second bracket 8 and the adjusting seat 12 can be either a fixed connection or a movable connection, both of which enable the sharpening of the tool. However, this utility model preferably uses a movable connection, as detailed below.

[0026] The second bracket 8 is movably connected to the adjusting seat 12 via a tensioning member 11. One end of the tensioning member 11 is fixedly connected to the adjusting seat 12. The second bracket 8 can rotate around the tensioning member 11 with a single degree of freedom. A tension spring 18 is provided between the second bracket 8 and the base 1. The tensioning effect of the tension spring 18 not only ensures normal operation but also allows the second bracket 8 to rotate around the tensioning member 11, shortening the distance between the driving wheel 9 and the driven wheel 10, thus facilitating the removal of the sanding belt. Furthermore, to facilitate the installation of the tension spring 18, the second bracket 8 is provided with a right-angled portion 14 for installing the tension spring 18. In this utility model, the tensioning member 11 includes a locking piece 110, a rod 111, a blocking piece 112, and an anti-loosening bolt 113 that cooperates with the rod 111.

[0027] Preferably, the device also includes a speed control box 3, which is electrically connected to the motor 4 via wires. This is a prior art method for adjusting the speed of the motor 4, and will not be described in detail here.

[0028] Preferably, the adjusting seat 12 is a profile part with a row of grooves.

[0029] In any of the above embodiments, the base includes a base plate 15, and a shock-absorbing rubber 13 is provided under the base plate 15 to make the sanding belt support frame for the sharpening machine more stable during operation. In addition, a tensioning component can be added to ensure the sharpening effect. The tensioning component can adopt existing technology.

[0030] An adjustment mechanism includes an adjustment seat 12 stacked on a base 1. One end of the adjustment seat 12 is movably connected to the base 1 via a vertical shaft 7. The other end of the adjustment seat 12 is provided with an adjustment assembly on the base 1 for rotating the adjustment seat 12 in accordance with the base 1. The mechanism also includes a bracket for connecting a drive wheel 9 or a driven wheel 10, the bracket being connected to the adjustment seat 12. The principle and use of this adjustment mechanism are described in the section on the working principle of a belt sander support frame for a knife grinding machine, and will not be repeated here.

[0031] Preferably, the bracket and the adjusting seat 12 are movably connected by a tensioning member 11, one end of which is fixedly connected to the adjusting seat 12. The bracket can rotate around the tensioning member 11 with a single degree of freedom. A tension spring 18 is provided between the bracket and the base 1. In this embodiment, the connection method and structure of the bracket, tensioning member 11, adjusting seat 12, and tension spring 18 can be the same as those of the second bracket 8, tensioning member 11, adjusting seat 12, and tension spring 18 in the above embodiment, and will not be described again here.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
